Set Launch Options Wont Work!

[ADRevange]

I installed the game Unturned. When I was in the game I pressed the fullscreen button and the game made the resolution to big for my computer. It appears a black screen with a blue square in the middle where it says 94.5 Hz / 60 Hz.
I had this problem to Dota 2 about one year ago. I went in the Se Launch Options and i put there my resolution with the comands "-w 1280 -h 1204" and it worked. Now, when I try for Unturned it won't work. I tryed -windowed or -sw or -autoconfig. Nothing happens.
After I put the comand and click OK then Close and then come back my comand is still there.
I tryed the comands -autoconfig or -sw and -windowed for Warframe , Guns Of Icarus and Primal Carnage but they don't work, just like the Unturned.
What is the problem? Why my Launch Options worked about an Year ago but now they won't?
Can somebody help?

You have to find the particular parameters for that game.

It might be better if you ask in the game's forum, but try this:

Or try to find the file that stores the settings for the game. Delete it, so you get the default one again. (Dont delete by pure guess!)

Or press alt+return to get into windowed mode, and change the settings. (Or the mac equivalent)

You should write your question in the game forum
